AUXILIARY SUPPORT.,

Specicationof Letters Patent. Application filed .T uly 29, 1912.l SerialNo. 711,950.

Patented Apr. it, ieri.

Ain which the object to be operated upon is required to be held in anoblique position while the work is being accomplished, said vises,chucks, etc., for metal workin being usually mounted upon milling,saping, drilling and grinding machines which as a rule themselvesareequipped with a base upon which they can be swiveled around avertical axis to facilitate the adjustment for angular cutting.

This improvement relates particularly to an aum'liary support which isplaced between the vise or chuck proper and its ordinary swivel base.The object of this particular construction of auxiliary support is topermit the ready adjustment and rigid locking of the vise at any desiredangle, that is, tipped sidewise at the same time as forward or back,with either a horizontal or vertical plane in other object is to give tothe vise or chuck to which my auxiliary support is applied' universalmotion and rigid locking. in any desired position, within therequirements of either machine or bench work.

Figure 1 is a view in front elevation of a support in accordance withthis invention, showing the same mounted in supporting position beneatha vise. Fig. 2 is a view in side elevation of the same. Fig. 3 is acentral vertical section of the support taken on line C-,D of Fig. 5.Fig. 4 is a similar view taken at right angles tothe line of section ofFig.. 3, or upon line A-B of Fig. 5, and

Fig. 5 1s a top plan View of the support.

rihe members 8 and 9 constitute the principal elementsof'my'inventionand each consists of a cylinder having two plane ends or faces one endvotea'ch being a cross section at right angles toftle cylinder axis andtherev fore circularinfform arid thetherend cr face of each cylinderbelng a section formed States, re-

words, my

by a plane oblique to the axis of the cylinder and therefore ellipticalin form. The two cylinders are so joined that the oblique or ellipticalfaces are in `Contact and as the degreeof Obliquity is preferably thesame in each, it follows that in one position the two together form aright cylinder. The member 8 may be rotated in a complete circle uponthe member. 9 by means hereafter described.

As shown in Figs. 3, 4, and 5 the upper I member 8 is provided on itstop with an annular slot 'or recess 10, which receives the clampingbolts 11, by which the vise proper 2 is secured to member 8, and on thebottom of the member 8 is an annular flange l2 which -iits into theannular recess 13. This recess 13 is on top of the lower member 9 and isfor the purpose of receiving said `flange 12 and the clamping bolts 14by which the upper member 8 1s secured to the lower member 9. The top ofthe member 3 is also provided with an annular slot 15 to receive theannular flange 19 upon the bottom of 9 and also to accommodate theclamping bolts 16, which serve the purpose of securing the members 8 andv9to the member' 3 after 8 and 9 have been adjusted as a whole around avertical axis.

As will be seen, the top flange on the upper member 8 is provided withgraduations for the purpose of indicating the angularity 0f the vise 2around a vertical axis, while the lower flange of the upper member 8 isprovided with graduations to determine the Obliquity of the top surfaceIof the upper member 8 upon which the vise 2 is clamped. The bottom angeof the lower member 9 is also provided with graduations for determiningthe angularity of the vise in whatever tilted position .it may be,around a vertical axis.

The upper member Sis provided with a hole 17 and the lower member 9 witha hole 18 as seen in Fig. 4f, said holes being for the purpose ofreceiving handles to facilitate their adjustment.

While the application of my auxiliary support is shown in connectionwith a milling-machine vise, it is in no way coniined to this type oftool, but can be applied to lathe chucks, drill press chucks, benchvises, lixtures, etc., or to the ordinary bench vise "where compoundyangular positions of the work holders are required,and while l haveshown the members 8 and 9 having their adjacent surfaces in a certaindegree of obliquity with the axis of the combined members, it is evidentthat this Obliquity may be changed in angle, andI that the adjacentsurfaces of the two members' and 9- may be of any desired degree ofoblqi/quity.

Having thus described my invention what I claim as new and wish tosecure by Letters Patent is, for the purpose described:

In an auxiliary support, two cylindrical members superposed one upon theother, the upper member having its top face at right angles to the axisof the support and its lower face at an oblique angle to said axis, thelower member having its upper face oblique to match with the obliqueface of the upper member and its lower face at right angles to the axisof the support, both of said members provided in their upper faces withan annular inverted T-shaped slot, an annular flange on the lower faceof the upper member slidabl received in the slot in the upper face of teA lower member,J clampingl sitioned bolts positioned through saidflange and having their heads slidably received in the slot in the lowermember for securing said members inadjusted relation, opposite recessesin the sides of said upper member adjacent the oblique edges thereof,adjusting nutsv upon the free ends of said bolts and poin said recesses,clamping bolts having their head secured in the slot in the upper memberadapted for securing the support to the object to be supported, angularity and 'Obliquity indicating graduations positioned respectively uponthe periphery of `thetop and bottom flange of the upper member, `andangularity indicating graduations upon the bottom of the lower member.

In testimon whereof I aix my signature in presence o two witnesses.
